Effluent Phosphorus Removal

A dataset containing daily observations from the J.D. Philips Resource Recovery wastewater treatment facility from June 2, 2020 to February 11, 2021. During the biological nutrient removal (BNR) phase of the wastewater treatment process, the plant uses biological filters to remove nutrients such as phosphorus and nitrogen. However, they are incapable of removing all nutrients, especially biological phosphorus. Supplemental carbon, in the form of whey, is essential to the removal of biological phosphorus. Because whey was limited during the collection of this data, the facility made changes including dosing with acetic acid, changing the primary clarifier sludge blanket levels, and making other modifications with the goal to efficiently lower biological phosphorus levels. The facility was designed with anaerobic, anoxic, and aerobic zones. YSI Inc./ Xylem Inc. sensors were used in the basin in Zones 2, 5, and 7, which are shown in the process diagrams included with this dataset. This dataset can be used to identify which variables may impact the concentration of phosphorus in the effluent of the wastewater treatment plant.
